There3D printing technologycould revolutionize the photovoltaic sector but for now it is thesolar powerto go to the aid of3D printing with low environmental impact innovation. A3D printerpowered by sunlight, the purpose of this app? Turning desert sand into glass.
There are many 3D printing projects but few engineers go into glass processing. The device was developed by the German designer Markus Kayser, it is called Sinter Solar and uses thesolar powerto provide useful heat for turning desert dust into glass.
The3D printersthey use laser technology to create solid and precise shapes. For now, the starting materials, those that replace the ink of 2D printing, have been plastics, resins or metal powders. Markus Kayser's device replaces dust with desert sand and electricity to operate the laser with solar energy.
In the deserts of the Middle East and North Africa, natural resources are abundant but given the extreme conditions of these environments, man has not yet been able to exploit them. Rather than building power grids and transporting large drills, Sinter Solar allows the production of various forms of glass starting from3D printing technologyand from the sand, no cables are required because energy is provided by sunlight.
Sinter Solar uses a large lens designed to capture sunlight with minimal thickness. The lens rotates and follows the sun's rays so as to capture the light and exploit it to melt together the layers of sand contained within the3D printer. The result? Thereprinterproduces glass objects of all kinds. The shape of the glass object to be printed can be downloaded onto a memory card which transmits the data to the machine.
Kayer developed the first prototype of3D printerwhich produces glass as early as 2010. Over the past three years, there has been no shortage of implications: during his studies at the Royal College of Art in the United Kingdom, Kayser was able to carry out a careful cost analysis, the result? There3D printingit is well on its way to becoming far cheaper than traditional glass production.
The convenience is clear: once you buy the lens (cost about $ 600!) And connected to a high-precision 3D printer, there will be no more expenses to be faced as the raw material (sand and energy) is completely free!
